Cheshire Police has launched a murder investigation following Martin Conway's disappearance, with four people arrested in total.

The 39-year-old was last seen in Chester city centre overnight between Sunday 1 February and Monday 2 February, 2026.

Despite extensive enquiries carried out since he was reported missing, Martin has still not been found. While no body has been recovered, detectives believe he may have come to harm.

A 35-year-old woman from Winsford and a 37-year-old man from Northwich have also been arrested on suspicion of murder and released on bail pending further enquiries.

Detective Inspector Andrea Price said: "Martin was last seen over four months ago, and during that time we have been following multiple lines of enquiries in an effort to trace him. We now believe he may have come to harm.

"Following an extensive investigation, we have now arrested four people in relation to his disappearance who are assisting us with our enquiries.
